[SOLVED] Motherboard missing psu pins

[themourqsreks]

Hello there everyone!

Yesterday I found out that my prebuilt PC's motherboard, a Fujitsu D3222-A12, has 2 psu ports. An 18-pin one, and a 24-pin one. My psu is already connected to the 18-pin port, but there is no port on where it should be for the 24-pins. Just a black spot with 24 silver dots on top of the board. Here is the motherboard's manual https://www.manualslib.com/manual/606720/Fujitsu-D3220.html?page=5#manual . Any solution on that one?

Thanks

maybe the board come in several variates, some requiring 24 pin power and others 18. You just happen to have the 18 pin version.

is there a reason you ask?

 

[themourqsreks]

Yea, can't I just take it to a technician and install the 24-pin input port on the MB?

 

[stevenjemint]

You could, but i wouldn't recommend it.

There may be components on the board designed to work with the 18 pin power delivery but not the 24 pin.

What is the reason you want a 24 pin connector on the board?

Because my psu output is 24 pin and I can't find another way to power the card any ideas?

Read this old thread - http://www.tomshardware.co.uk/answers/id-2279543/pin-motherboard-psu.html

Unfortunately you will not be able to put a standard PSU on this motherboard.

For the effort and risk of getting it to run on a standard PSU you'd be better off using a different board/set up.

So the only solution is to buy a new motherboard? I don't know if I have the funds for that. Can't a technician add the missing 24 pins? Can't I just buy an 18 to 24 pin adaptor from Amazon?

Like i said. You could do this, but you don't know that the components on the board will be compatible.

Maybe when fujitsu fit this board with a 24 pin connector the put different chips on the board to handle the difference in power delivery.

Why is this a problem? You said your PSU is connected to the only power socket on the board no, the 18 pin one, so what is the problem? Did the PSU die? There are adapters which will turn a 24pin supply into and 18pin supply but not the other way around obviously, so if you have a 24 pin PSU you want to use to power the 18 pin board you can try that.

An no, I think the chances of a technician being able to "add" a 24 pin supply are extremely slim.... if your board wasn't designed for a 24 pin supply then the wiring all over the board would probably have to be reconnected.

Would probably be cheaper to buy a new PSU than a new mobo though no?

well its proprietary 16pin, ull need psu from fujitsu
and u cant use adapter, voltages seems to be different then on ATX PSU, for example your mobo has 11V standby, atx has 5V there

My current psu is pretty weak, 250W. I plan on buying the Corsair VS650, and install it. Current psu has 18-pin output, and the Corsair has 24-pin output. My motherboard has both a 18-pin, AND a 24-pin input, but the 24 one is just missing
Here is how the motherboard looks like https://www.manualslib.com/manual/606720/Fujitsu-D3220.html?page=5#manual

The term you're looking for here is "proprietary". This motherboard was designed this way on purpose. The idea is to make it so you cannot upgrade your system and, hopefully when the time comes, you'll purchase another new computer from the same company.

No tech is going to attempt to install a 24-pin PSU connector and if they did, they would certainly charge you more than the cost of a new motherboard.

Time to start saving for a new computer.

Then I just have to buy a Fujitsu psu?

 

[kerberos_20]

well its 16+8, dunno where u see 18
24+4 is used on D3222-B board, and u got A board

Look at the top-left and the 4-Pin CPU. You'll note there are 12(?) additional dots there. In the previously linked image, that is where the power cable connects.

Check the diagram I have sent. There are CLEARLY 18 pins on the top left port and 24 on the mid right one

 

[themourqsreks]

Won't a simple 24to18 pin adaptor cable do the job?

here i zoomed it for you including some random numbers on it

 

[themourqsreks]

Lol you're right. Sooo no other way than replacing the motherboard?

 

[kerberos_20]

pretty much new mobo or getting some fujitsu compatible PSU, btw that 16pin isnt the only power your mobo has, on right side that 8 pin SATA power plug is that other power plug which normal ATX psu doesnt have
